Hi all I'm having a few problems with my r34 gtt rb25dett neo it's completely stock. It's done 200,000 just got rebuilt with forged rods and pistons. Running 7 psi on the stock turbo. Iv driven it another 4,000 km roughly and I noticed about a week ago in 3-4 grand rev range in 2,3 and 4th gear it would lose power upon acceleration. But I drove it today. And it's having the same sort of issue but only when I get boost like runs fine in first but if I hit second and get past 1 psi of boost it like jerks and loses pretty much all go to it. The original issue i couldnt hear the engine really struggling i just sort of felt the lose of power but the issue im having now i can definently hear the engine die. It also hunts slightly when idling I'm thinking it's a fuel issue iv ordered a pump, reg and coil packs. I was just wondering if anyone else has had this issue. It still gets boost if I power through i get to 6 psi and it doesn't feel like it changes or gains more power.
Alrighty my driving issues sorted not low on power no more I did check for a boost leak using carry cleaner awesome f*king idea BTW nothing happened, then checked the tps voltage was good and changed with the throttle position. I also unscrewed and tested it didn't get a change in revs. I changed the spark plugs and now it's all sweet. My idle still slightly varies about 50 to 100 rpm but not frequently. Thank for the help BLOOODY LEGENDS
